The operation of the hyperthermia device will be described below. When the power switch (corresponding to the main power switch 9 in FIG. 1) of the hyperthermia device 1 is pressed, a display as shown in FIG. here,
Select whether to perform heating (warming mode) or to perform device utility (utility mode). That is, in the operation panel 26 as shown in FIG. 5, when a forward switch 61 is pressed, a heating mode is set, and when a return switch 62 is pressed, a utility mode is set. Of the switches on the operation panel 26, valid switches (here, the forward switch 61 and the return switch 62) are turned on, and invalid switches (for example, setting switches) are not turned on. By turning on the effective switch, the operator can easily operate. This is possible using switches with LEDs. First, the heating mode will be described. The utility mode will be described later.

When the heating mode is entered, the monitor display shows FIG.
Is displayed, and an instruction to connect the applicator is issued to connect the lumen applicator 28a and the extracorporeal applicator 28b to the device. At this time, a temperature measurement value of the connected temperature sensor 27 is displayed on the upper right portion of the monitor screen as shown in FIG. Up to four channels can be connected, and are called A channel, B channel, C channel, and D channel, respectively. FIG. 6 shows an example where the temperature is all 40 ° C. This temperature display is displayed up to a screen (FIG. 22) indicating the collection of the cooling water. When the switch 61 of the operation panel 26 is pressed after the connection of the applicator is completed, the monitor display becomes FIG.
8a is filled with cooling water. At this time, return switch 6
Pressing 2 returns to the previous screen (FIG. 4). In the screen for filling the cooling water in FIG. 7, the state in which the cooling water is filled in both the lumen and the extracorporeal applicators 28 a and 28 b is shown by sequentially overwriting the screens shown in FIGS. 8A to 8F. Displayed as a movie. When the filling of the cooling water is completed, the operation panel 26
Switch 61 is pressed. Here, when the return switch 62 is pressed, the screen returns to the previous screen.

Next, a screen for setting heating conditions as shown in FIG. 9 is displayed. Here, the heater temperature, the applicator temperature, the heating time, and the high-frequency output are set. The heater temperature indicates the temperature of the cooling water. The applicator temperature is measured by a temperature sensor 2 installed on the surface of the lumen applicator 28a.
7 shows the control temperature of FIG. The heating time counts the time from when the control temperature is reached. The high frequency output sets the maximum output value of the high frequency output at the time of temperature control.

Each of the above-mentioned settings is performed by each setting switch on the operation panel 26. The switch 61 which advances each time one setting is performed is pressed. If the return switch 62 is pressed here, the previous setting is returned. When the setting of the high-frequency output is completed, an instruction is made to make a final check of all the set values. If there is a mistake in the setting in this final check, the setting is reset by each setting switch. If it is OK, the forward switch 61 is pressed.

At this time, a screen as shown in FIG. 10 is displayed on the monitor 25. Here, the lumen applicator 28
In order to insert a into the patient's body cavity, the cooling water is once suctioned to deflate the balloon. This situation is shown in FIG.
As shown in (c), the image is displayed as a moving image by sequentially overwriting on the screen. This process automatically ends in 10 seconds. If the return switch 62 is pressed within this 10 seconds, the screen returns to the heating condition setting screen.

After 10 seconds, a screen as shown in FIG. 12 is displayed on the monitor 25. Here, an instruction is given to insert the lumen applicator 28a into the body cavity of the patient. Also in this case, as shown in FIGS. 13A to 13J, the state of insertion is displayed as a moving image by sequentially overwriting on the screen. This display shows a state in which the lumen applicator 28a is inserted into the esophagus 29, but is not limited thereto. As shown in FIG. 14A, a treatment site such as a rectum or a gynecological region is shown. As shown in (b), it may vaguely indicate a living body.

When the insertion of the lumen applicator 28a is completed, the advance switch 61 of the operation panel 26 is pressed. Then, the monitor display becomes as shown in FIG. 15, and the process shifts to the step of recirculating the cooling water. Here, when the return switch 62 is pressed, the process returns to the setting of the heating condition.

In the step of refluxing the cooling water, the pressure and flow rate of the cooling water are adjusted according to the steps shown in the flowchart of FIG. Flow rate is 100 ml / min, pressure is 800-120
0mmH adjusted within a range of ₂ O.

First, the cooling water driver 22 shown in FIG. 3 is set to the valve mode 1 (step S1). This is a mode in which the cooling water pressure is increased or decreased by increasing or decreasing the rotation speed of a pump for circulating the cooling water. Thereafter, the pressure is measured (Step S2). Here, when the pressure is 1000
mmH ₂ O is determined (step S3).
For 1000mmH ₂ O or less to increase the rotational speed of the pump (step S7). If the pressure exceeds 1000 mmH ₂ O, the valve mode is set to 2 (step S4), and the flow rate is set to 10
Set to 0 ml / min. The valve mode 2 is a combination of valves in which a cooling water loop between the pump and the lumen applicator 28a is closed.

Next, the pressure of the cooling water is measured (step S).
5), the pressure is determined whether between 800~1200mmH ₂ O (Step S6), 800 to 1200
If it is between mmH ₂ O, the adjustment is automatically terminated. In other cases, it is determined whether or not the pressure exceeds 1200 mmH ₂ O (step S8). If the pressure exceeds 1200 mmH ₂ O, the initially set pressure is reduced from 1000 mmH ₂ O by 100 mmH ₂ O (step S9), and step S1 and subsequent steps are repeated. . Also, 8
If it is lower than 00 mmH ₂ O, the pressure is increased by 100 mmH ₂ O (step S10), and the steps from step S1 are repeated.

In this way, the adjustment of the pressure and flow rate of the cooling water is automatically terminated, and the process proceeds to the next step. However, when the switch 62 which returns before the automatic termination is pressed, the process returns to the previous step. Next, FIG.
The tuning unit 23 adjusts the tuning. At this time, a screen as shown in FIG. 17 is displayed on the monitor 25. Here, the value of the variable element of the tuning unit 23 is changed by the tuning switches 1 and 2 of the operation panel 26 to adjust the high-frequency reflectivity to 3% or less. As a variable element of the tuning unit 23, a variable capacitor, a variable inductor, or the like is used. The reflectivity is the ratio of the high-frequency output power to the reflected power, and a small value indicates that the high-frequency energy is used efficiently for heating. In normal use, this value should not exceed 10% at most. When tuning is completed, switch 6 on operation panel 26 is advanced.
Press 1. Pressing the return switch 62 during tuning returns to the cooling water adjustment.

At this time, a screen as shown in FIG. 18 is displayed on the monitor 25 to indicate that preparation for starting heating is completed. Here, when the start / pause switch is pressed, heating is started. Pressing the return switch 62 returns to tuning.

When heating is started, first, the temperature is set for 30 seconds. After that, the high frequency is actually output from the high frequency power supply 24 and the temperature is controlled. The temperature of the affected part is detected by the temperature sensor 27 installed on the surface of the lumen applicator 28a, and the control unit 21 acquires this. The control unit 21 compares the measured temperature with the applicator temperature set under the heating condition, calculates the value of the high frequency to be output, and issues a command to the high frequency power supply. At this time,
The output high frequency is controlled so as not to exceed the value of the high frequency output set under the heating condition.

At first, a temperature around the body temperature is measured, but when a high frequency is output, the temperature rises. The heating time starts to be counted from the time when the highest temperature among the measured temperatures exceeds the applicator temperature set under the heating condition. In other words, the heating time set under the heating condition is not the time during which the high frequency is output, but the time during which the temperature of the affected part is controlled substantially to the applicator temperature.

When the heating time has elapsed, the display shown in FIG. 19 is automatically displayed, and the cooling water in the balloon of the lumen applicator 28a is sucked so that the cooling water is easily extracted. 20
After a second, the process automatically proceeds to the next step. This state is displayed as a moving image by sequentially overwriting the screen as shown in (c) to (a) of FIG.

Next, a display as shown in FIG. 21 is made on the monitor 25, and both the internal and external applicators 28a and 28b are displayed.
Is instructed to remove the applicator from the patient's body. In this case, moving images are displayed by sequentially overwriting the screen as shown in FIGS. Switch 61 that advances when removal is completed

A moving image is shown by sequentially overwriting the screen as shown in FIGS. This process is automatically completed in about 3 minutes, and a screen as shown in FIG. 23 is displayed. Here, it is instructed to clean and disinfect the applicator, tubes and cables, and then clean up. Here, when the advance switch 61 is pressed, the process proceeds to the next step. When the return switch 62 is pressed, the cooling water is removed again for three minutes.

Next, a screen as shown in FIG. 24 is displayed on the monitor 26. Here, data on the patient is input in order to save the heating data. That is, the input key of the operation panel 26 is used to input the ID number, the number of treatments, the patient's age, sex, and the date on which the treatment was performed. When entering numbers, press the desired key after pressing the numeric key. When inputting a character, the character key is pressed until the character to be input is displayed on the screen of the monitor 25.
When the desired character is displayed on the screen of the monitor 25, the corresponding key is pressed and input. To move from the ID number to another input item such as the number of treatments, press the enter key. When it is desired to correct the input character, the character is deleted by a BS (backspace) key, and then the correct character is input.

When this input is completed, the switch 61 is pushed. The display as shown in FIG. Here, when the input key 1 is pressed, the temperature data is output to both the floppy disk and the printer. Pressing 2 outputs the temperature data to the floppy disk.
Pressing 3 outputs temperature data to the printer. The data entered on the floppy disk is
The set values set under the heating conditions and the temperature data every two seconds are recorded and stored. The data, the set value, and the temperature data input by the data input are printed as a graph on the printer. When the output is completed, the advance switch 61 is pressed. This switches to the screen shown in FIG. 4 and returns to the initial screen. Here, when the return switch 62 is pressed, the process returns to the data input.

Next, the utility mode will be described. Pressing the return switch 62 on the initial screen shown in FIG. 4 changes the monitor display to a screen as shown in FIG.
Here, three types of utilities can be selected and are called a utility menu. Here, pressing the input key 1 selects data re-output. Pressing the input key 2 selects the date and time setting. Pressing the input key 3 selects a format. Here, pressing the return switch 62 returns to the initial screen of FIG.

When the data re-output is selected by pressing the input key 1, a screen as shown in FIG. 27 is first displayed. Here, a list of data recorded and stored on the data disk is displayed. These are recorded and saved in the heating mode data output. Here, the number of the data to be output is input with the input keys. Select No. 20 to return to the utility menu. Here, the screen is switched to the screen as shown in FIG. 28, and the output destination is selected. Pressing the input key 1 displays a temperature graph on the monitor 25. At this time, a screen as shown in FIG. 29 is displayed. Pressing the input key 2 prints the temperature graph on the printer. When the input key 3 is pressed, this screen is terminated and the data list is displayed (FIG. 27). If you select date and time adjustment,

According to the second embodiment, the surgeon can easily perceive the state of the cooling system by looking at the monitor display. In addition, since the cooling water pressure and the flow rate are automatically set, there is no troublesome operation, and even an operator who is unfamiliar with the apparatus can easily operate the apparatus.

Hereinafter, a third embodiment will be described. The configuration of the third embodiment is the same as the configuration of the above-described second embodiment, but differs in the flow of cooling water adjustment. FIG. 32,
The flow of the cooling water adjustment according to the third embodiment will be described with reference to FIG.

First, the valve of the cooling water driver 22 shown in FIG. 3 is set to mode 1 (step S21). As described above, the cooling water line is set by the valve so that the cooling water pressure is increased or decreased by increasing or decreasing the rotation speed of the pump for circulating the cooling water. Here, the pressure P is measured (step S22). The initial value of the pressure P is 1000mmH ₂ O. Therefore, step S2
In step 3, it is determined whether or not the pressure P has exceeded 1000 mmH ₂ O. In the following cases, the rotation speed of the pump is increased to increase the flow rate in step S36. When the pressure P reaches 1000 mmH ₂ O, the mode is set to the valve mode 2 (step S24). The valve mode 2 is a state in which the cooling water recirculation path between the pump and the bore applicator 28a is closed as described above. Thereafter, the cooling water flow rate is set to the flow rate expected during treatment (step S2).
5). Here, it is assumed that the flow rate = M, but M is, for example, 1
It is 00 ml / min. Further, the number of adjustments N is increased by one. The adjustment count N is set to 0 at the start of the adjustment. Therefore, N = 1 here.

Thereafter, this state is continued for 10 seconds (S
26). This is because the cooling water is a fluid and requires a predetermined time until the state is settled. Next, to measure the pressure P (step S27), the pressure P is treated expected range (800~1200mmH ₂ O) whether the determined (step S28), ends when in this range. Also,
If not, it is determined whether the pressure P exceeds 1200 mmH ₂ O (step S29). If it does, the flow from step S30 is performed. That is, it is determined in step S30 whether or not the number of adjustments N is the first time. In the case of the first time, the valve mode 1 is set (step S31).
P is set to 1000 mmH ₂ O (step S3)
2). In the case other than the first time, P = 1200 mmH
_It is set to ₂ O (step S37).

Next, the pressure is measured (step S33), and it is determined whether the pressure at this time is lower than the previously set pressure P or the lowest flow rate (flow rate = L) (step S3).
4) If No, the flow rate is reduced until the determination in step S34 becomes Yes (step S38). Next, in step S35, it is determined whether or not the number of adjustments N is the second time. In the case of the second time, the process ends without performing any further adjustment. In the case of the first time, the flow from step S24 is executed again.

On the other hand, when the pressure is 80
If it is found that the value is lower than 0 mmH ₂ O, the flow from step S39 in FIG. 33 is performed. First, it is determined whether or not the number of adjustments N is the first time (step S39). If it is determined that it is the first time, the valve mode 1 is set (step S40), and P is set to 1000 mmH ₂ O (step S41). . In other cases, P = 800 mmH ₂
O. Next, the pressure is measured (S42), and it is determined whether the pressure at this time exceeds the previously set pressure P or is the highest flow rate (flow rate = H) (step S43), and the determination in step S43 is Yes. The flow rate is increased until (Step S45). Next, the process shifts to step S35 in FIG. 32 to determine whether or not the number of adjustments N is the second time, and in the case of the second time, the process ends without performing any further adjustment. In the case of the first time, the flow after step S24 is performed again.

According to the third embodiment, since the cooling water pressure and the flow rate are automatically set, there is no troublesome operation, and an operator who is unfamiliar with the apparatus can easily operate the apparatus. In this embodiment, the number of adjustments is limited, so that the time required for adjustment can be reduced.

The problems and objects to be solved by the conventional techniques and the invention for the above-described structures (1) to (7) are as described above, but the conventional techniques and the invention for the structures (8) to (16) are not. The problem to be solved and the effects of the invention are as follows. (Prior Art) There has been known a hyper-mirror apparatus for treating a living body by using two electrodes and inserting one electrode into the living body. In the applicator shown in FIG. 39, the electrode 300 to be inserted into the living body is usually provided with an electrode in order to prevent a burn of the surrounding area (mucous membrane) and enable electrical connection between the electrode 300 and the living body. Cooling means including a balloon 301 is provided so as to cover 300, and is generally called a lumen applicator. On the surface of the balloon 301, a temperature sensor 302 for measuring the temperature near the affected part of the living body is provided. The end of the applicator connected to the hyperthermia device has a cooling water input / output port 3
03, an electrode terminal 304, and a temperature sensor terminal 305.

An operation procedure for performing a treatment using a hyperthermia apparatus will be described below. First, the balloon 301 is once filled with cooling water so that air is not mixed. At this stage, it is confirmed that there is no leakage of the cooling water from the balloon 301. Then, balloon 3
The balloon 301 is deflated by sucking the cooling water in 01. This is because when the electrode 300 is inserted into a living body, the balloon 3
01 is in the way. After insertion, balloon 301
Is again inflated to bring the lumen applicator into close contact. At this time, the cooling water input / output port 303
The flow rate and pressure of the cooling water from the tank.

Thereafter, a high frequency current is applied between the two electrodes to perform heating. After the heating is completed, the cooling water in the balloon 301 is once sucked in order to remove the lumen applicator from the living body. After removing the lumen applicator, finally, the cooling water circulated through the lumen applicator is sucked into the device, and the lumen applicator is removed from the device to perform cleaning and disinfection. (Problems to be Solved by the Invention) As described above, since the operation of inserting the applicator into the living body is complicated, it is not easy to train the operator. When the surgeon uses this device, the operator operates the device with one hand. I needed to. This, in addition to prolonging the treatment time, can cause mental anxiety for the patient being treated.

After the applicator is inserted into the living body, the cooling water is recirculated. At this time, since the applicator is not visible from the outside, some skill is required to adjust the pressure and flow rate of the cooling water. Required. This has also become one of the factors that complicate the operation of the apparatus.

The hyperthermia apparatus of the present invention has been made in view of such a problem, and its purpose is to display the state of supply and discharge of the fluid supplied to the applicator in a manner that is easy for the operator to understand. Another object of the present invention is to provide a hyperthermia device that can automatically operate a device by automatically controlling supply and discharge of a fluid, thereby shortening a treatment time. (Effect of the Invention) According to the present invention, the state of supply and discharge of the fluid to be supplied to the applicator is displayed to the operator in an easy-to-understand manner, so that the operator can easily operate the apparatus. The treatment time can be shortened. In addition, the operator does not hesitate about how to perform the operation during the treatment, and the patient does not have to worry. Further, since the supply and discharge of the fluid is automatically controlled, even an operator unfamiliar with the device can easily operate the device.

[0063]

According to the present invention, the operator can check the state of the fluid recirculation unit and exchange fluids without moving the operating position while operating the hyperthermia device. At the time of maintenance, repair of the fluid recirculation unit can be easily performed while operating the apparatus. Further, since the fluid supply port is on the patient access side, the number of conduits connecting the fluid recirculation unit and the applicator is minimized, and the relay conduit is not obstructed.
